Cant add funds to apple id/cant edit payments
So I am apart of a family sharing account with a primary payment method. Now, normally I can just add funds from my personal apple wallet without charging the primary payment method. However now all of a sudden I am no longer able to add to my account without using a physical giftcard or my primary method of payment which is not my own. Is there a way to fix this or am I SOL?
